湿度是一个重要的气象学参数,在水文、气象、海洋等领域里尤为重要。然而,在工农业生产部门如纺织,化工、制药、电子元器件制造、农业科研等,湿度,同样也有着重要的实际意义,这些部门都对湿度参数提出严格的要求,所以湿度的测量,早被人们所注视和研究。自1783年萨修尔发明毛发湿度计以来,将近二百年时间,不们一直沿用着这一方法.进 Humidity is an important meteorological parameter, which is especially important in hydrology, meteorology and oceanography. However, humidity also has important practical significance in the industrial and agricultural production sectors such as textiles, chemicals, pharmaceuticals, electronic components manufacturing, agricultural research, etc. All of these departments place strict requirements on the humidity parameters, so humidity measurement Be people’s attention and research. This method has not been adopted by nearly two hundred years since Sauter invented the hair hygrometer in 1783.
